linux开发中的C++资料，比较全，以前老师给的，要学习C++的同学不妨下去看看(linux development of learning materials, based on the C++)

用BCB6.04编写的舍6入5看齐，奇进偶不进的数值修约法 根据GB8170—87《数值修约规则》［2］及GB3101—93附录B《数值修约规则》［3］，修约时不能简单地采用“4舍5入”的办法。应遵循的原则是：①拟舍弃的数字的最左一位数字等于、小于4，则舍去；大于、等于6，则进1。②拟舍弃数字的最左一位数字等于5，若其右边数字并非全部为“0”时，则进1；其右边数字皆为“0”时，所拟保留的末位数字若为奇数则进1，若为偶数或“0”则不进。(BCB6.04 prepared with care in line 6 to 5, Ki Jin Jin does not even repair some of the numerical method in accordance with GB8170-87 Numerical revision of the rules [2] and GB3101-93 Appendix B Numerical revision of the rules [3], when revision can not simply use 4 homes 5 in approach. Should follow the principle is: ① to give up most of the figures, a figure equivalent to the left, less than 4, then rounding greater than, equal to 6, then enter 1. ② figures to be the most left-up a digital equivalent to 5, if not all of the right figure for the 0 , then enter 1 its right figures are 0 when the bottom of the figures to be retained if it is an odd number into 1, if an even number or 0 does not enter.)

1、文本串非空且以文件形式存放，统计匹配的词集非空。文件名和词集均由用户从键盘输入； 2、“单词”定义：由字母构成的字符序列，中间不含空格字符且区分大小写； 3、待统计的“单词”在文本串中不跨行出现，它或者从行首开始，或者前置若干空格字符； 4、在计算机终端输出的结果是：单词，出现的次数，出现的位置所在行的行号，同一行出现两次的只输出一个行号； 5、测试数据：将实验的源程序作为测试文件,从中任意选取“单词”作为测试的词集。 ( 1, a text string not empty and with the file form deposit, statistics matching word set not empty. The file name and word set all by users from keyboard input 2, the "words" definition: from letters constitute sequences of characters, and the space character among excluding case-sensitive Three, to the statistics "words" in the text string not an inter-bank appear, it first started from line or, or lead some space character 4, on a computer terminal of the output result is: the words, in the frequency of, appear in the position of the line number did, with a line of output only twice in a line Numbers 5, test data: will the source program as the test files, to freely choose the "words" as a test of the word set. )

用C#编的简单的画图工具，模仿Windows里的画图工具。( This is a simple program,which is developed with C#. )

dma驱动开发程序，使用ddk开发，例子典型，有学习的价值。(dma ddk driver)

有关三维插补的程序，自己做一个数据库，记录一些数据点的插补值，可通过补偿算法，算出其他点的插补值(The 3 d interpolation procedures, own a database, record the data point of some interpolation value, but through the compensation algorithm, work out the other points interpolation value)
